I've always loved maps, but I'm here with a specific question.

Perhaps someone could tell me the best sub-forum in which to post.

My wife and I have a very, very small business. We sell audioguides and the product includes a pdf booklet with a map or two.

Our current product will have a map of a city with (if I can figure out how) specific sites marked on it.

My problem is that I cannot find a public domain map without a lot of stuff on it already.

So, where should I post this question to have the best chance of getting some dialog going?
